IMPROVEMENT 1N INKs'rANDs.

' The Schedulel referred to in these Letters Paten-l: and making part of the same.

To dll whom/t may concern Be it known that I, SAMUEL DARLING, of Providence, iu the State of Rhode Island, have invented certain'Improvements iu vInkstands; and I dohereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention suicient to-enable those skilled in the art to practice it.

My improvements consist ,inv a special construction of the inlistand-itself; and also in an inkstand having e a hollow elastic stopper, to avoid any compression of the -air within the stand when the stopper is pressed 1n.

One form in which I have embodied my'improvements I have illustrated in the accompanying drawing, in which-` and Figure 2, a central Avertical section of the Same, showing my novel features.

Figure 3 is ha plan view of the lower part before the top hasbeeu put on; and

Figuresll and 5 are plan views, respectively, ofthe stand with the 'elastic stopper removed, and oi' the top partor piece as seen on its under side.

I make my iukstand of two or mere parts, but preferably of two, as shown, when made of glass or other molten, molded, or cast material, as such material admits of forming the lower part or reservoir in the `s'amepiece with the elevated ink-chamber contained wit-hin it, as also with the pen-gauge.

A is the lower part or main reservoir. B, the elevated ink or dipping-cup, having walls around it of proper height, as seen in the drawing,

the chamber formed by these walls constituting, in connection with the deep cavity G, the pen-gauge or dipping-gauge, the object of such gauge being to de- .terminc and limit positively, by the height ofthe walls, the amount oi'.- ink to betaken upon the pen, which ink can never have a depth greater than the 'prescribed height oi' the walls permits.

projecting annular wall, to prevent the ink from falling out when the inkstand is tipped or inverted, either to supply the ink-trougl1 from the main reservoir A, or by accident, or when traveling.

Ihe hole F is for theA escape of air when the inkstand is being supplied with ink, which is' done through `the dipping-hole or cup E, this hole l being kept Figure 1 represents an elevation of an inkstand;

tightly coi-lied or closed when the i'nkstaud is iu use. It is also used for pouring out from the stand any ink or water whenever necessary. The ink-chamber B, it will he seen, is quite sliallow, as' it is not necessary to contain much -ink at a time; and the pen-gauge'O is a deep, gradually-tapering cavity, having its-largest diameter (which is at the top) less than vthe breadth of any ordinary pen, thus preventing positively any descent of the-pen beyond a predetermined point,`the tip o'f the 'pen being also, by reason oi' the depth' of the chamber of this gauge, prevented from ever touching bottom, and iijoln being thereby injured, orfrom picking up any sediment which might collect there. l The deeper the walls of the ink-chamber B, the

` greater vwill be the quantity ot` ink the pen can take.

up-at adip.

rI he supply of 'ink should not be more than the the bore of the tube.

' With ordiinu-y'solidstopper-s, when they' are pressed down tightly, the air is compressed inside of the inkst-and, and for thc purposes for which it is more especially designed,namely, for childrcns and family use, and for traveling, this is objectionable, because when somewhat hcate'd'(aud` even when not) the compressed air has a tendency to force out the ink around the stopper when the stand gets inverted and much damage and inconvenience result.

In using my stopper, itshead or b ulb is compressed between the thumb and finger as itis about to be applied, and a portion of the air expelled from it, so that it will admit of being pressed down int-o the month o r tubeoi' thc inkstand without leaving any compressed air within, as a part of the air is -i'ree to rise in thestoppcr to supply the vacuum previously created therein.

A thin pipemay, if thought desirable, b e inserted so as to close the the upper part, constructed tially as described.
